Estimating and Making Plan. It is vital for the success of software development project of any size. Plans guide for the funding decisions which usually be Budget & Time.
For example : Before initiating a brand new project if we tend to estimate it to require One year with a price of one million however would reject a similar project if we predict it’d take Two years with a price of 2 million.
Generally planning helps us to know what needs to be available to work on task for a given time period. Correct Planning helps us to know and track the status of project functionality that users need and expect for. Without making plans we open our projects to any number of troubles. The team that does no planning cannot answer the most basic questions, such as “when will it be done? ” and “when to schedule the product launch?”. The team that over plans, their plan can be more thorough, but that doesn’t always imply it is going to be accurate correct or useful.
The uncertainty suggests that during the feasibility phase of a project an estimated schedule is typically as far off as 60% to 150%. And a project expected to take 30 weeks. After the requirements are written, the estimate might still be around +/- 15% in either direction. So an estimate of 30 weeks means the work takes 25 to 34 weeks.
Why Planning is Required?
A plan is like a map with sequence of actions which is followed to achieve some specific goal. It is an effective way to reduce the necessary time and effort in achieving the goal.
One of the principal reasons why we need planning is The 80/20 Rule. This rule is well established for unstructured activities. By the numbers, it says that 80 percent of the outcomes come from 20 percent of the inputs. As PARETO validated with his research “RULE” holds true, in a very rough sense, to 80/20 ratio.
A good planning process is always supported by
- Risk Planning increases the likelihood of project success by providing insights into the project’s risks.
- A plan must always convey expectations and describes an opportunity of what may come to pass over the course of a project. A plan does not assure exact features on a specific date at a unique cost. However, it is based on a set of expectancies with assumptions.
- To reduce uncertainty in the project. The team generates new ideas in the project with the help of technologies. It’s far more important that new ideas be stated into an iteration plan which is designed to assist a team to refine their vision and prescient of the product
- Reliable delivery of the promised features builds trust between the developers of a product and the client.
“Everything has a past. Everything – a person, an object, a word, everything. If you don’t know the past, you can’t understand the present and plan properly for the future.” – Chaim Potok, Davita’s Harp
